Single and pregnant

So I broke up with my ex before I even found out I was pregnant. He's very toxic! I'm going to be raising this baby alone (luckily I have my bff to help me) along with my 4 year old son. I'm nervous bc it was so hard the first time being alone and I just need some lady friends who are going to be single moms as well..

Ps. He already knows but he lives 2 hours away, doesn't have a car, he's homeless, and he only calls me when he wants something. He keeps trying to make me feel bad that he's on the streets so I'll come save him like always but after the craziness he's put Me thru that will never happen again! He put himself into this mess by going to the casino and spending his rent money instead of paying his bills 🤦‍♀️. He's young and I'm not sure he'll ever grow up and take responsibility.
